E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This pilot study primarily aims to verify the feasibility of practicing the combined approach on GIST patients treated with imatinib, evaluating: 1. The proportion of patients successfully monitored according to the protocol among the enrolled patients; 2. The time required for Cmin determination with conventional and new strategies for a simplified sample collection (DBS and microcapillary tubes); 3. The time required for giving the clinicians the results of the combined analysis (Cmin and ctDNA). |
Valutare la fattibilità di un nuovo approccio per il monitoraggio simultaneo delle concentrazioni plasmatiche di farmaco e dello stato mutazionale del tumore attraverso l’analisi del ctDNA con il fine di valutare eventuali variazioni nell’esposizione al farmaco ed individuare possibili marcatori precoci di resistenza al trattamento in pazienti affetti da GIST e trattati con imatinib. La fattibilità verrà valutata in termini di: 1. Numero di pazienti monitorati con successo secondo il protocollo sul totale dei pazienti arruolati. 2. Tempo richiesto per il TDM con la metodica convenzionale e con nuove strategie per la raccolta semplificata del campione (Dried Blood Spot (DBS) e microcapillari) 3. Tempo necessario per fornire la risposta dell’analisi combinata Cmin-biopsia liquida ai clinici |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the possibility to early detect tumour progression through ctDNA analysis in patients’ plasma samples in course of treatment. • To verify the possible correlation between imatinib exposure and response (TTP), overall and by tumour mutational subtype; • To validate a point-of-care-testing (POCT) TDM (electrochemical biosensors and molecularly imprinted polymers);
|
• Valutare la possibilità di identificare precocemente, tramite l’analisi di ctDNA, la progressione di malattia. • Verificare la possibile correlazione tra l’esposizione di imatinib e la risposta (in termini di tempo alla progressione) stratificando i pazienti in base allo stato mutazionale del tumore • Validare nuove metodiche per il TDM (biosensori elettrochimici e molecularly imprinted polymers);
